Title: 3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P106B; Evaporative Emission System Pressure
Sensor - Secondary Air Injection Pressure Sensor Correlation; 2015 MY Tundra [08/2014 - ]
DTC
P106B
Evaporative Emission System Pressure Sensor - Secondary Air Injection
Pressure Sensor Correlation
DESCRIPTION
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P106B
The pressure detected by the canister pressure sensor (Vapor Pressure
or Air Pump2 Pressure (Absolute)*) differ by 6.98 kPa (52 mmHg) or
more
(2 trip detection logic)
Canister pressure
sensor (Leak
detection pump)
Air switching
valve assembly
HINT:
This DTC is stored when a deviation from pressure sensor characteristics is detected.
The pressure detected by the canister pressure sensor and the pressures detected by the pressure sensors of
both air switching valves (for Bank 1 or Bank 2) are checked 55 minutes after the ignition switch is turned off.
If the pressure detected by the canister pressure sensor and the pressure detected by the pressure sensor of
either air switching valve differ by a certain amount, the MIL is illuminated and a DTC is stored (2 trip
detection logic).
HINT:
Correct judgment may not be possible when the altitude is 4000 m (13120 ft.) or more.

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on [A].
2.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Start the engine and idle it for 10 seconds [B].
4.
Turn the ignition switch off.
5.
Soak the vehicle for 55 minutes [C].
6.
Turn the ignition switch to ON and turn the Techstream on.
7.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].
8.
Read the Pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
9.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
10.
3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P106B; Evapo...
Input the DTC: P106B.
11.
Check the DTC judgment result.

INCOMPLETE
DTC judgment not completed
Perform driving pattern after confirming DTC enabling conditions
N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform steps [A] through [D] again.
12.
If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning
If no permanent DTC is output, the system is normal.
13.
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition
1.
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P106B)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / DTC.
(e) Read the DTCs.

READ VALUE USING TECHSTREAM (VAPOR PRESSURE PUMP, AIR PUMP
PRESSURE (ABSOLUTE) AND AIR PUMP2 PRESSURE (ABSOLUTE))
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menu: Powertrain / Engine and ECT / Data List / Vapor Pressure Pump, Air
Pump Pressure sensor (Absolute) and Air Pump2 Pressure sensor (Absolute).
(e) Compare the Vapor Pressure Pump, Air Pump Pressure sensor (Absolute) and Air Pump2
Pressure sensor (Absolute) data from the Data List with the current atmospheric pressure*.
